Thanks for the answers guys, I kind of figured it was ACT.
Max777, getting rid of the ABS delete kit is on the agenda for sure. I have still been entertaining the thought of keeping ABS, but I still can't stomach the cost of the new pump. As to the rust, I guess it is not that bad, just looks bad. I am noticing some crushing at the jack points though under the runners, that has me a bit worried too. I do plan to do some serious grinding on the engine bay one of these weekends.
